High-Intensity Interval Training (HIIT) is described as a succession of short duration and maximum or near-maximum intensity efforts, alternated by recovery periods during which exercise continues at a lower intensity (active recovery) or is interrupted (passive recovery). Our objective was to evaluate the acute responses of three HIIT protocols of different work/rest interval times over the total time of the session, with self-selectable load and up to exhaustion, "all out".The sample was composed of 22 male participants ( = 22) between 19 and 24 years old. The HIIT protocol consisted of one of the three HIIT protocols, of 30, 60 and 90 s density ratio 1:1 and with passive rest, with a total exercise duration of 10 min. The test was performed in a cycloergometer set in workload mode independent of the pedaling frequency. The comparison of the three HIIT protocols shows that the duration of the work/rest intervals, starting from 30 s of work, in the cycloergometer, there are no significant differences in the levels of lactate concentration in the blood, nor in the heart rate, since a similar amount is obtained in the three protocols. The percentage of maximum power developed reached in each HIIT protocol is related to the duration of the working intervals.
高强度间歇训练（HIIT）被描述为一系列短时间的、最大强度或接近最大强度的运动，其间穿插着恢复期，在恢复期内，运动以较低强度持续进行（主动恢复）或中断（被动恢复）。我们的目标是评估三种不同工作/休息间隔时间的HIIT方案在整个训练时间内的急性反应，负荷可自行选择，直至“全力”耗尽。样本由22名年龄在19至24岁之间的男性参与者组成（n = 22）。HIIT方案由三种HIIT方案之一组成，密度比为1:1，工作/休息时间分别为30秒、60秒和90秒，采用被动休息，总运动时长为10分钟。测试在一台与蹬踏频率无关的工作量模式的自行车测力计上进行。三种HIIT方案的比较表明，从30秒的工作时间开始，在自行车测力计上，工作/休息间隔的时长不同，但血液中乳酸浓度水平和心率均无显著差异，因为在三种方案中获得的数值相似。每个HIIT方案中达到的最大功率百分比与工作间隔的时长有关。
